【问题描述】：
我正在关注一个要求我安装 express 的 MEAN 堆栈教程：
我运行这个：
npm install -g express-generator
这是我的结果：
username@username-Inspiron-3521:~$ npm install -g express-generator
/home/username/npm/bin/express -> /home/username/npm/lib/node_modules/express-generator/bin/express
express-generator@4.13.1 /home/username/npm/lib/node_modules/express-generator
├── sorted-object@1.0.0
├── mkdirp@0.5.1 (minimist@0.0.8)
└── commander@2.7.1 (graceful-readlink@1.0.1)
但是当我这样做时
express --ejs flapper-news
The program 'express' is currently not installed. You can install it by typing:
sudo apt-get install node-express
我做错了什么？
感谢您的时间。

当我做npm install
username@username-Inspiron-3521:~/Documents/mean/flapper_news$ npm install
npm ERR! install Couldn't read dependencies

在运行 npm install -g express 并输入 express -v 后，我得到了这个：
bash: /usr/bin/express: No such file or directory

这是我的.bashrc 文件：
### Added by the Heroku Toolbelt
export PATH="/usr/local/heroku/bin:$PATH"
export PATH="$PATH:$HOME/.rvm/bin" # Add RVM to PATH for scripting
export PATH=$HOME/local/bin:$PATH

【问题讨论】：
-
也可以使用
npm install -g express。参考这里stackoverflow.com/questions/23367534/… -
@aishwatsingh 这不是必需的。快递生成器与快递几乎没有关系。它所做的只是安装一个使用 express 的应用程序，express 将在下一步安装。
-
根据模块的npm doc，你必须使用$ npm install安装依赖。你试过吗？

@KevinB
npm install -g express-generator安装成功，但在那之后，它应该自动安装 express，它没有或它没有但它的路径是错误的，我真的不确定这里有什么问题。 -
@TGrif 我在运行
npm install后编辑了问题@
